Best Answer

A transparent latch (or simply a latch) is a digital logic device that can store two stable states with a level sensitive control signal called enable/latch, when this control signal is in the enable state the latch device transparently passes its input signal to its output, when this control signal is in the latch state the latch device holds its output in the current state and ignores the input signal.

This behavior is different from flip flops (e.g. D flip flop), which are usually clocked and often edge sensitive not level sensitive.

What is a latch in microprocessor?

A latch is a type of flip-flop circuit that is used to store digital information in a microprocessor or other digital system. A latch is essentially a digital memory element that can hold a single bit of information (i.e. a "1" or "0"). Latches can be used to store data that needs to be held temporarily, such as the current state of a program, or to create a temporary buffer for data that is being moved between different parts of a system.

Latch are just like inputs which are used to set or reset the output for a given combination.


Draw a schemetic to demultiplex bus ad0-ad7 using any octal latch in 8085 microprocessor?

The 8085 microprocessor is used IC 74LS373 to latch the address of 8085. Basically latch is consists of 8 flip flops. Generally we used D-flip flops (Delay).The clock of these flip flops are connected together and available as a output pin called enable.Working : The address will appear on AD0 AD7 lines. The ALE will go high and forcingEnable = 1. This will make latch enable and ready to work. Before address disappears ALE = 0. This will make latch disable. AD0 - AD7 will now be used as data bus.Hence, AD0 - AD7 (low order) address bus of the 8085 microprocessor is multiplexed (time-shared) with the data bus. The buses need to be demultiplexed.
